OIL SEPARATOR.

Application filed November 22, 1.927. Serial-No. 235,108.

This invention relates to an oil separator adapted to remove from theexhaust steam of. steam engines the oil contained therein 1 and has forits object to provide an improved apparatus of this character.

The invention comprises a series of separating cylinders of corrugatedcross section with a prefixed conoidal passageway respectively, wherebythe separation of the oil from the exhaust steam is eifected on the waythrough the said separating cylinders .and the oil is ejected into thecasing enclosing the said separating cylinders with drainage through anumber of the small orifices provided at the prominent points or peaksof the corrugations of the said separating cylinders for that purpose,by the pressure of the exhaust steam.

The invention is illustrated in the accompanying drawings, in which IFig. 1 is a, vertical sectional view of an oil separator embodying theinvention. I

Referring to the embodiment of the invention illustrated in Figs. 1 and2 the casing 1 is of a cylindrical form, whilst its bottom or lower partforms a drain receiver 2 of a rectangular cross section, and is providedwith legs 3 for mounting the device.

\Vithin the casing 1 are arranged in series a'number of the separatingcylinders 5 which are of a corrugated cross section, in other words arelongitudinally or obliquely corrugated as shown in Figs. 3, 4 and 5 andare provided with a number of small orifices 6 at every prominent pointor peak of the corrunations, for ejecting the oil and drain separatedfrom the exhaust steam passing through the same. Around eachseparatingcylinder an annular space 4 is provided, which communicateswith the drain receiver 2 at the lower part.

Each of the separating cylinders 5 is disposed behind an inlet conicalmember 7 for directing the exhaust steam against the corrugated wall ofthe same, which consists of an outer wall 8 of frusto-conical form andan inner wall 9 of substantially conical shape connected together by thewebs 10 or any other suitable means, and slightly projects intp the saidseparating cylinder at its rear en The fore end cover 11 of the casing 1is formed with aninlet branch 12 and an inlet annular cone for theforemost separating cylinder, whilst the rear end cover 13 is formedwith an outlet branch 14.

Within the drain receiver 2 are arranged the division plates 15 forpreventing the incoming oil and drain ejected from one of the separatingcylinders 5 from splashing upon the other separating cylinders.

In operation, the exhaust steam flowing in the inlet branch 12 of theend cover 11 of the casing 1 in direction of the arrow from the steamengines, first will pass within the foremost conical separating cylinderthrough the foremost inlet member, striking against its corrugated wall,where a portion of the oil contained in the exhaust steam is separatedtherefrom and ejected to the drain receiver 2 through the orifices 6, atthe peaks of the corrugations by the pressure of the exhaust steam, andwill pass to the subsequent cylinder where the oil is separated andejected in the similar manner and so on, and finally will pass to theoutlet branch 14 of the rear end cover 13 of the casing 1. The oilcontained in the exhaust steam on the way of the exhaust steam from theinlet branch 12 to the outlet branch 14 will be separated with the drainby the separating cylinders and will stay in the drain receiverwherefrom the same will be drawn oif by any suitable means through thedrain cook 16.

In a modification illustrated in Figures 6 and 7, the separatingcylinders 5 are arranged sectionally .1n series in a curved casing 17.

In this case, the separating cylinder located in the curved part of thecasing is spaced :1. suitable distance apart from separating cylinderslocated in the straight parts of the casing for reason of theconstruction, andthe drain receiver of each section is connected to thedrain cock 16 by means of a drain pipe In a modification illustrated inFigs. 8,

and 9,-the separating cylinders 5 are arranged side by side in parallelbut in opposite direction in two rows in a casing 19, a di-v visionplate 20 being provided betweenvthe rows of the separating cylinders,and the adjoining extremities of the two rows of the separatingcylinders being in communication with each other by a junction box 21formed at the end cover 22. The end cover 22 is also formed with anoutlet 23 and a conical inlet member 7. The other end cover 24 is formedwith. an inlet branch 25, a conical inlet memher 7 and an outlet branch26. The exhaust steam of the steam engines will flow into a row of theseparating cylinders through the inlet branch 25 and thence another rowthrough the junction box 21 and the inlet member 7, and finally willpass to the outlet branch 23 as indicated by the arrows.

In a modification illustrated in Figs. 10, 11 and 12, the separatingcylinders 5 are arranged in three rows in a casing 27 03f substantiallytriangular cross section, one row being centrally located upon the lowertwo rows located side by side. These rows are separated by divisionplates 28 and 29 provided within the casing. A pair of the adjoiningextremities of the lower rows is communicated with each other by ajunction box 30 formed in an-end cover 31. The end cover 31 is alsoformed with an outlet 32, inlet member 7, and an outlet branch 33. Atopposite side of the said junction box, the extremity of the upper rowcommunicates with 1,72aess engines will flow into one of the lower rowsof the separating cylinders through the inlet branch 36 and inlet member7, and thence into another lower row through the junction box 30 andconicalinlet member 7 and thence upper row through the junction box 34and conical inlet member 7 and finally pass to the outlet branch 33 asindicated by arrows.

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to be performed, I declare thatwhat I claim is 1. An oil separator, comprising a casing having a drainreceiver, a number of separating cylinders of corrugated cross sectionhaving a number of small orifices at every outwardly extending peak ofthe corrugations arranged in a series in the casing, a pair of conicalmembers prefixed to every separatingcylinder to form a conoidal inletand division plates arranged in the drain receiver.

2. An oil separator, as set forth in claim 1, in which the separatingcylinders are arrangedin a series in a curved casing.-

3. An oil separator, as set forth in claim 1, in which the separatingcylinders are arranged in series in a casing in two rows side by side. I

In testimonyv whereof I have signed. my name to this specification.
